SPRING BED-BOTTOM.

SPECIFICATION formingpart of Letters Patent No. 275,476, dated April 10,1883.

I Application led September 13, 1882. (No model.)

To all whom it may concern:

Be tknown that I,GEoRGEW.F1sHEE1NG,a citizen of the United States,residing at Allegheny, in the county of Allegheny and State ofPennsylvania, have invented a new and useful Improvement in SpringBed-Bottoms, of which the following is a specication'.

, My invention relates to an improvement in spring bed-bottoms, andrelates particularly to those bed-bottoms in which are used doubleconical spiral springs, and is designed to obviate the necessity of anyhook arrangement to connect said springs.

In the accompanying drawings, Figure 1 is a plan view, looking at thetop, of a .spring bed-bottom, showing my invention. Fig. 2 is aperspective view ol' a small section containing two spirals.

Similar letters refer to similarparts throughout the different views.

The slats A, secured to the end blocks, B, constitute thebed-'rame, towhich the springs -are secured. The springs c of the double spring G areinserted in and stapled to the slats A at the point s. Then the springsb are pressed through the space e of the adjacent spring, so as tointerlock the top spire ot' the spring a. with the t'op spire ot thespring b at the point a'. The ends of the wire which forms the springs bare inserted in and secured to the slats A at a point distant from thepoint of insertion s of the spring a equal to the distance across thetop or largest spire of said springs. 1n a like manner the springs c andd are pressed through the space e of the adjacent spring, so as tointerlock, and Vsecured to the slats at equaldistances apart, and so onwith as many springs as are required to lill the bed-frame. To giverigidity to the springs lengthwise over the bed, the ends of each seriesot springs are connected with the end blocks, B, by means of a chain orwire,f, interlocking with the said springs, and firmly stapled to top ofthe end blocks, B.

Having thus described my invention, what I desire to claim and secure byLetters Patent In a spring bed-bottom, the combination of two or moredouble conical spiral springs, having the largest or top spire of eachspring that forms the pair intcrlocked with the largest spire of eachadjacent spring that forms a similar double spring, substantially asdescribed, and for the purpose specified.
